Organelles do NOT have a single uniform pH.
And if you think they must, because “protons diffuse fast,” this paper is for you.

The first paper of my PhD is now available as a preprint! 🎉
Transposable elements (TEs) don't just jump within fungal genomes, they also move extensively between species. In this study, we screened over 1,300 fungal genomes and found a conservative estimate of 5,500+ horizontal transfer events.

We identified a plasmid vector for the strain and generated a large RB-TnSeq library, screening for genes impacting plastic degradation.
